Managed Agents.

AI agents that run on infrastructure a model provider hosts and maintains, so teams can deploy an agent without building or operating the servers behind it.

Also known as Hosted agents, server-hosted agents

What it is

A working definition of Managed Agents.

Managed agents are AI agents that run on infrastructure a model provider operates directly, rather than on servers a company builds and maintains itself. In 2026, major model providers began offering managed agent platforms: you describe the task, permissions, and tools an agent needs, and the provider handles execution, scaling, and uptime.

This is different from simply calling an API. A managed agent can hold a task for hours, use multiple tools in sequence, and pick back up after interruptions, all without a company’s engineering team writing the orchestration layer that makes that possible.

Why ad agencies care

Why Managed Agents matters in agency work.

Agencies have wanted AI agents for repetitive account work for a while. Managed agents removes the main obstacle, which was needing engineers to build and babysit the infrastructure.

It lowers the technical bar to deploy an agent. an agency without a dedicated engineering team can stand up an agent that monitors campaign performance or pulls weekly reporting, because the provider runs the underlying servers

It shifts the vendor evaluation question. when a partner pitches an AI agent product, agencies should ask whether it runs on managed infrastructure from a known provider or on custom infrastructure the vendor built and maintains alone, since that affects reliability and support

It changes internal staffing conversations. agencies that once needed to hire a developer to build agent tooling can now evaluate managed agent options as a build-versus-buy decision, similar to how they’d evaluate any SaaS tool

In practice

What managed agents looks like inside a working ad agency.

An agency running paid social for a dozen mid-size clients builds a managed agent that checks each account every morning for budget pacing issues, flags creative fatigue, and drafts a Slack summary for the account lead before the 9am stand-up. The agency’s one technical hire configures the agent’s permissions and connects it to the ad platforms’ reporting APIs in an afternoon, without provisioning a single server. When the agent needs to run a multi-step check across a client’s Google and Meta accounts back to back, it keeps working through the sequence unattended, something the team previously handled with a shared spreadsheet and a Monday-morning scramble.

Build AI workflows that actually run through The Creative Cadence Workshop.

The automations and agents module of the workshop teaches you how to build AI workflows that compress the busywork without taking the craft out of the studio.
